Is the pressure analysis of the diesel tank correct?
Thread Content
In a typical diesel storage tank, since the saturated vapor pressure of diesel is below 1 atmosphere, if there are no other gases present in the tank, the pressure inside the tank is lower than the external pressure, right?
But how can you ensure that there are no other gases present in the initial state under normal circumstances? You also can’t create a vacuum
Saturated vapor pressure of diesel (kPa): 37.1 at 20°C~~~ What does the original poster want to say?
Obviously not; generally, diesel storage tanks are equipped with vents, and regardless of the vapor pressure of the oil inside the tank, the pressure inside it remains roughly equal to or slightly higher than atmospheric pressure.
No, the pressure inside the tank is higher than that outside;; gauge pressure = absolute pressure – atmospheric pressure
